.SH DESCRIPTION
A valuator is a representation of the state of an input device in
terms of a physical quantity such as length.  A valuator event, of
type \fBgii_val_event\fR, reports a change in any of those quantities.
.SH GENERATED EVENTS
This structure is used for the \fBevValRelative\fR and \fBevValAbsolute\fR
events.
.SH STRUCTURE MEMBERS
A valuator may be either absolute or relative, like pointer motion
events.

To interpret the numbers, query valuator device info with the
\fBGII_CMDCODE_GETVALINFO\fR command code.
